Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a trigeminal neuralgia cryotherapy device. BACKGROUND

[0002] As a common cranial nerve disease, traditional treatment of trigeminal neuralgia often uses drug control or surgery, but there are limitations such as drug dependence and large surgical trauma. Cryotherapy gradually becomes an important choice due to its minimally invasive and reversible characteristics. It selectively destroys pain nerve fibers through low temperature. However, the existing cryotherapy device has the following defects: Insufficient positioning stability: the operation depends on the doctor's hand-held needle, and slight movement of the patient's head can easily cause the needle to shift, resulting in treatment position deviation or nerve injury, especially for the fine trigeminal nerve branch area, displacement errors can cause serious complications; Low temperature control precision: cryogenic energy is easy to diffuse to non-target areas, making it difficult to accurately limit the range of action. Clinical data shows that about 20% of patients have temporary facial numbness after surgery, mainly due to cryogenic damage to adjacent sensory nerves. The existing technology lacks effective intraoperative nerve protection mechanism.

[0003] High operation complexity: the traditional device lacks multi-degree-of-freedom adjustment structure, and the doctor needs to maintain a fixed gesture throughout the operation to stabilize the needle body, which can easily cause hand tremors due to fatigue, increasing the risk of surgery, and is particularly unfriendly to novice doctors.

The outer end of the inflatable water bag is communicated with a drain pipe for discharging medium, and the distal end of the drain pipe extends to the outside of the barrel and is connected with a water outlet pipe. The outer end of the pressing seat is also sealingly connected with a gas inlet pipe for conveying frozen gas, the end of the gas inlet pipe is communicated with a gas passage extending along the inside of the needle, and the end of the gas passage is connected with a gas outlet pipe for discharging gas; The end of the positioning assembly is fixedly connected with the wearing assembly, so that the positioning assembly and the needle body assembly are stably fixed at the treatment position through the wearing assembly.

[0006] Further, the positioning assembly comprises a positioning seat, the bottom end of the positioning seat is provided with a first damping rotating shaft, the bottom end of the first damping rotating shaft is connected with a swing rod, the bottom end of the swing rod is provided with a second damping rotating shaft, and the bottom end of the second damping rotating shaft is connected with a threaded head.

[0007] Further, the positioning seat rotates through the first damping rotating shaft, and the swing rod rotates through the second damping rotating shaft.

[0008] Further, the direction adjusting assembly comprises a first transverse rotating shaft, the top end of the first transverse rotating shaft is provided with a first steering seat, the inner side of the first steering seat is provided with a damping telescopic rod, the other end of the damping telescopic rod is connected with a second steering seat, the top end of the second steering seat is connected with a second transverse rotating shaft, and the outer end of the second transverse rotating shaft is fixedly provided with a connecting seat.

[0009] Further, the first steering seat rotates through the first transverse rotating shaft, and the damping telescopic rod rotates through the first steering seat and the second steering seat.

[0010] Further, the second steering seat rotates through the second transverse rotating shaft, and the second steering seat is annularly distributed with three groups at the outer end of the connecting seat.

[0011] Further, the connecting seat is fixedly connected with the cylinder body, and the cylinder body is sleevedly connected with the pressing seat.

[0012] Further, the water inlet pipe is communicated with the inflatable water bag through the water passage, and the inflatable water bag is communicated with the water outlet pipe through the water outlet pipe.

[0013] Further, the wearing assembly comprises a helmet, the top two ends of the helmet are provided with a docking head, and the inside of the helmet is provided with a locking buckle.

[0014] Further, the docking head is symmetrically distributed along the vertical center line of the helmet, and the docking head is connected with the threaded head through threads.

[0015] The present application provides a kind of trifid neuralgia cold treatment device, with following beneficial effects: 1. In this invention, medical staff put on and lock the helmet for the patient to ensure that the head is fixed. Then, the threaded head at the end of the positioning component is screwed into the helmet connector to achieve a rigid connection between the treatment unit and the head. This design allows the treatment unit to remain relatively stationary as the head moves synchronously, effectively eliminating the risk of misalignment of the insertion point and needle dislodgement caused by the patient's head movement, and improving treatment stability and patient comfort.

[0016] 2. In this invention, medical personnel hold and pull the positioning seat, adjusting its position through the rotation of the first and second damping shafts to precisely align it with the patient's trigeminal nerve. The suspension and positioning effect of the damping shafts ensures that the positioning seat remains stationary after positioning. After positioning, the medical personnel push the pressing seat downwards within the cylinder, causing the needle to be inserted into the affected area. Subsequently, by applying force with the wrist, the cylinder angle is adjusted, allowing the needle to be oriented precisely to reach the target trigeminal nerve branch. During cylinder angle adjustment, the damping telescopic rod extends and retracts accordingly through the rotation of the first steering seat, the first lateral shaft, the second steering seat, and the second lateral shaft. Its damping property keeps the cylinder angle stable after adjustment, providing precise, stable, and auxiliary support for needle positioning. This design effectively overcomes the risks of needle deviation or nerve damage caused by hand tremors in traditional handheld operations, and is especially beneficial for novice or fatigued doctors to perform high-precision operations. Combined with the use of a helmet, it further enhances the surgical stability of the device.

[0017] 3. After the needle of this invention reaches the target trigeminal nerve branch, medical staff inject high-pressure carbon dioxide cryoprotectant at approximately 20°C into the inlet tube. The cryoprotectant circulates through the inlet tube, ventilation tube, and exhaust tube, and the nerve is cryotreated through the needle. Simultaneously, sterile hot water at approximately 40°C is injected into the water inlet tube. The water flows through the water inlet tube into the expansion bladder, causing it to expand and tightly surround the core of the treatment area, forming a dynamic temperature barrier. This barrier effectively absorbs and restricts the diffusion of cryoprotectant energy, protecting surrounding healthy nerve tissue and reducing the risk of postoperative facial paralysis. The water in the expansion bladder is discharged through the drain tube from the outlet tube at the top of the pressure seat. Medical staff can sense the temperature change of the flowing water by touching the outlet tube and dynamically adjust the hot water flow accordingly to ensure a continuous and reliable isolation effect. In addition, the expanded bladder positions the needle site, preventing displacement during treatment. This design, combined with the aforementioned positioning function, further enhances the treatment stability of the device. Attached Figure Description

[0021] To sum up, the trigeminal neuralgia cryotherapy device, in use, first, when the treatment starts, the medical staff wears the helmet 601 for the patient, and fastens the helmet 601 stably and fixedly on the head of the patient through the locking buckle 603 inside the helmet 601, ensuring that the whole device has a stable head fixing basis. After the helmet 601 is worn, the staff rotates the threaded head 105 at the end of the positioning assembly 1 into the adapter 602 at the top of the helmet 601, through which the treatment unit can be rigidly connected with the head, so that the treatment unit can displace synchronously with the head when the patient moves the head. At this time, the treatment unit is in a relatively static state, which can effectively eliminate the risk of misalignment of the insertion site caused by the patient moving the head during treatment and the risk of needle 502 falling out during treatment caused by moving the head, thereby effectively improving the treatment stability of the device. At the same time, this also enables the patient to move the head during treatment, which also improves the comfort of the patient during treatment. Then, after the threaded head 105 and the adapter 602 are connected, the medical staff holds and pulls the positioning seat 101, which can be adjusted by the rotation of the first damping shaft 102 and the second damping shaft 104. This enables the positioning seat 101 to accurately align with the position of the trigeminal nerve of the patient. Because the damping shaft has excellent hovering and positioning effect, it can ensure that the positioning seat 101 will not move after positioning. After the positioning seat 101 is positioned, the medical staff pushes the pressing seat 501 inside the cylinder 3 to move downward, and the needle 502 can move closer to the patient's affected part along with the downward movement of the pressing seat 501 until it is inserted into the patient's affected part. Then, after the needle 502 is inserted into the affected part, the medical staff can adjust the angle of the cylinder 3 by wrist force, which enables the orientation of the needle 502 to be adjusted, thereby ensuring that the needle 502 can accurately reach the target trigeminal nerve branch position. When the cylinder 3 is adjusted in angle, the damping telescopic rod 203 can be stretched or retracted by the rotation of the first steering seat 202 and the first horizontal shaft 201 and the rotation of the second steering seat 204 and the second horizontal shaft 205. Because the damping telescopic rod 203 has damping property, after the cylinder 3 is adjusted in angle, the damping telescopic rod 203 can keep the adjusted angle of the cylinder 3, which enables the needle 502 to be accurately and stably positioned during positioning, and the positioning has the effect of auxiliary support. Novice doctors and doctors after high-intensity surgery are prone to hand jitter during high-precision operation, which may cause the needle 502 to deviate or even harm the patient's nerves. Through the auxiliary support positioning, the instability of traditional handheld operation can be effectively overcome, and the surgical stability of the device can be further improved by cooperating with the use of the helmet 601. After the needle 502 reaches the target trigeminal nerve branch position, the medical staff injects the cryogen (high-pressure carbon dioxide gas, about -20 degrees Celsius) into the air inlet tube 508, which enters the air outlet tube 509 inside the needle 502, and is discharged from the air outlet tube 510, so that the needle 502 can effectively freeze the target trigeminal nerve branch. In addition, during the freezing treatment, the medical staff injects sterile hot water at about 40 degrees Celsius into the water inlet tube 503, and the water flow enters the inflatable water bag 505 through the water outlet tube 504 to inflate the inflatable water bag 505. After the inflatable water bag 505 is inflated, it tightly surrounds the core of the treatment area of the needle 502. At this moment, the inflatable water bag 505 forms a dynamic temperature barrier, which can effectively absorb and limit the spread of cold energy when the cryogen acts on the nerve through the needle 502, protecting the surrounding healthy nerve tissue from accidental damage, which can effectively reduce the occurrence of facial paralysis (tactile nerve freeze injury) in patients after the operation. Finally, the water in the inflatable water bag 505 is discharged from the water outlet tube 507 through the water outlet tube 506, which is specially arranged at the top of the pressing seat 501, so that the medical staff can directly feel the change of the water temperature in real time. Through this intuitive temperature feedback, the medical staff can immediately judge the heat efficiency of the isolation barrier, whether the water temperature is too low due to the influence of freezing, and dynamically adjust the flow of injected hot water to ensure the continuous and reliable isolation effect. In addition, the inflatable water bag 505 can locate the current position of the needle 502 after inflation, which can effectively ensure that there is no displacement during treatment. This design, combined with the above positioning function, can further improve the treatment stability of the device.
